ful Improvements in Splice-Bars, of whichthe following is a specification.

The present invention relates to meansfor connecting the ends of two rails for sustaining the same in alinement, and is in the nature of an improvement over the rail joint for which I was granted on May 12, 1914 United States Patent No. 1,096,696.

Another object of the invention is the construction and arrangement of parts whereby two rail ends may be effectively connected and sustained against lateral or vertical movement, but wherein the joint will not interfere with the longitudinal movement of the rails incident to the expansion and contraction thereof.

Other objects and advantages will appear as the nature of the improvement is more fully understood, reference being had to the accompanying drawings wherein there is illustrated a simple and satisfactory reduction of the invention to practice.

In the drawings: Figure 1 is a perspective view of two rails connected in accordance with the present invention, Fig. 2 is a top plan view, Fig. 3 is a transverse sectional view approximately on the line 3-3 of Fig. 2, Fig. 4 is a similar view approxi mately on the line 44 of Fig. 2, Fig. 5 is a detail perspective view of the supporting member, Fig. 6 is a similar View of the chair member, and Fig. 7 is a detail perspective view of the rail ends, looking toward the side thereof provided with the notches.

In the drawing, in which like characters of reference designate corresponding parts throughout, 11 designates two rails which have their ends abutting. The rails are of the ordinary construction, and the base flanges of the same have the edges cut away at an inward angle whereby, when the said rail ends abut. a V-shaned recess 2 is formed at the ends of said rails.

The numeral 8 designates a rail chair, which includes a horizontally straight longitudinally extending base 4 that has'formed on. one of, its longitudinal, edges, a vertical projection. 5', the same. having? an; integrally formed angular flange 6 which extends inwardly over the base, and which has its end formed with a vertical extension 7. The base 4 projects or extends a suitable distance beyond the vertical member 5, the said extending portion having notches arranged therein at suitable intervals to receive the shanks of spikes 8, the said spikes being driven into the supporting ties 9. Formedadjacent the opposite longitudinal edge of the base 4 is a vertically arranged side or plate 10, the same having its upper edge rounded inwardly to provide a lip 11, the lower face or wall of the said lip being arranged at an angle for a purpose which will presently be described. The inner face of the side or plate 10 at one end of the chair,

has a plurality of vertically arranged depressions 12 which communicate with open ings 13 in the lip 11, and which also communicate with pockets 14 in the base 4 of the chair 3. The base projects a suitable distance beyond the outer wall of the side or plate 10, the said projection being pr vided with a plurality of notches, each adapted to receive spikes 8 which enter the ties 9.

The numeral 17 designates the member which I term the support for the joint. This member includes a base plate 18 which is adapted to rest upon the base 4 of the chair 3 and to have its longitudinal edges contact with the vertical members 5 and 10 formed with the base 4. The longitudinal edge of and the underface of the lip 11, so that the said portion 19 will contact with both the inner faces of the member 10 and the lower angular face of the member 11, while integrally formed withthe vertical extension 19 is an angular flange 20 which extends inwardly of the base 18, overlying the same, and formed with the end of said flange 20 is a vertical plate 21. The rails 11 are adapted to have their base flanges rest upon the base 18 of the support 17, while one of the longitudinal edges of the base flanges of the said rails is contacted by the inner wall of the vertical extension 19 of the support, the upper angur lanface of said base being engaged. bythe flange 20, while the plate 21 contacts with the webs of said rails, the upper edge of said plate contacting with the underfaces of the heads of the rails. The opposite longitudinal edge of the base of the rail is contacted by the plate 5, the upper faces of the same being engaged by the flange 6, while the vertical extension 7 of the chair contacts with' the lower portions of the webs of the rails, as will readily be noted from the drawings.

' The vertical extension 19 of the support 17, at one of the ends of the said support-is provided with a plurality of vertically disposed depressions 22, one of which registers with one of the depressions 12 in the side or plate 10, so that the shank 23 of a headed pin or key 24 may be inserted through one of the openings 13 and passed through the registering depressions so that the lower portion of said key will be seated within one of the pockets 14 of the base 4 of the chair. As the head of the pin or key is arranged at a right angle to the shank thereof and as the upper portion of the side 10 is rounded, it'will be noted that a space is provided be tween the said head and the upper'portion of the side to permit of the insertion of a pinch bar so that the pin or key may be readily withdrawn to release the support from the chair when desired; v

The vertical side 10 of thechair which has its end provided with depressions12 is arranged at a. less distance away from the vertical member 5 of the said chair than is the said member 10 at the opposite end of the chair, and so it will be noted that the said member 10 is inclined from one of the ends of the chair to the opposite end, and likewise the member 19 of the support, which is providedwith grooves 22, is arranged at a less distance away from the opposite longitudinal edge of the base of the support than is the second or opposite end of the support. In other words, the portion 19 has its outer face gradually increasing in width and thickness from one of its ends to its opposite end and so the removal of the key to permit of the proper adjustment of the support with relation to the chair is highly desirable.

The flange 6 adjacent the vertical member 5 is provided with an opening 25 which is arranged centrally of the chair, and which registers with an elongatednotch 26 provided in the end of the base 18 which abuts with the wall 5 of the chair, while the base 4 of the chair is provided with an opening a 27 which registers with the opening 25, and

passing through the registering openings and through the elongated notch 26 is a pin or bolt 28 which is disposed within the V- shaped recess 2 in the ends of the rails and which serves as a means for preventing the creeping of the rails, after the same is arranged within the path of contact with the ends of both of the rails.

The vertical extension 7 of the flange 6 has its inner face provided with a longitudinally extending channel 30 which materially' adds to the flexibility of the said plate 7 so that the same will tightly contact with the webs of the rails and the said passage or channel may also provide for the recepltion of a bonding member between the rai s.

From the above description, taken in con nection with the accompanying drawings, the simplicity of the device, as well as the advantages thereof will, it is thought, be

perfectly apparent to those skilled in the art to which such invention appertains without a further detailed description.

Having thus described the invention, what I claim is: r

1. Ina rail joint, two abutting rails each having its base flange at one of'its edges notched at its end, an angular supporting plate upon which the rails rest, a joint chair for-the plate, and a pin passing through the support and through the base of the chair disposed between the notches at the rail ends.

base flanges of the rails and a vertical ex-' tension contacting with the webs and under lying the heads of the rails,'the said vertical member having its outer edge inclined from one end to the other, and provided with vertical depressions at its narrower end, a chair including a base upon which the base of the support rests and having a vertical member adjacent one of its longitudinal edges providel with an angular-flange and a vertically extending plate, said members adapted to engage with the sides of the rails opposite that contacted by the members of the support, the base of said chair being provided adjacent its other longitudinal edge with a vertical side having a rounded upper portion which terminates in a lip having an inclined wall which contacts with the inturned flange of the support, the inner wall of the said side plate being inclined from one end to the other end thereof, the

inner face of said side having a plurality of ber adapted to be moved longitudinally of the base to bring one of its depressions into register with one of the depressions in' the said side, a key including a shank and an am gular head adapted to be inserted through the In testimony whereof I afiix my signature opening in the side into the registerirllg dein presence of two Witnesses. pressions and to rest Within the poo et in the base, and means previded between the NATHAN DUBBIN' 3 chair and support disposed Within a notch at Witnesses:

the ends of the rails for preventing the L. B. ROBERTS, creeping of the rails. R. D. HICKS.
